We present a range of coding schemes for OFDM transmission using binary, quaternary, octary, and higher order modulation that give high code rates for moderate numbers of carriers. These schemes haveâ€¦ (More)

In 1999, Davis and Jedwab gave an explicit algebraic normal form for m!/2 - 2h(m+1) ordered Golay pairs of length 2mmiddot over Z2h, involving m!/2 - 2h(m+1) Golay sequences. In 2005, Li and Chuâ€¦ (More)

A numerical investigation is presented for the peak sidelobe level (PSL) of Legendre sequences, maximal length shift register sequences (m-sequences), and Rudin-Shapiro sequences. The PSL gives anâ€¦ (More)

The maximum known asymptotic merit factor for binary sequences has been stuck at a value of 6 since the 1980s. Several authors have suggested that this value cannot be improved. In this paper, weâ€¦ (More)

In 1999, Davis and Jedwab gave a direct construction of Golay complementary sequences over Zopf<sub>2</sub> <sup>h</sup> of length 2 <sup>m</sup>. Recently, Li and Chu found 1024 more quaternaryâ€¦ (More)

We present a recursive construction for difference sets which unifies the Hadamard, McFarland, and Spence parameter families and deals with all abelian groups known to contain such difference sets.â€¦ (More)

A classical problem of digital sequence design, first studied in the 1950s but still not well understood, is to determine those binary sequences whose aperiodic autocorrelations are collectivelyâ€¦ (More)

We argue that a Golay complementary sequence is naturally viewed as a projection of a multidimensional Golay array. We present a three-stage process for constructing and enumerating Golay array andâ€¦ (More)

The origin of all 4-phase Golay sequences and Golay sequence pairs of even length at most 26 is explained. The principal techniques are the three-stage construction of Fiedler, Jedwab and Parkerâ€¦ (More)
